Description

Technical Field

[0001] This invention relates to the field of elevator safety protection technology, specifically to an elevator car buffer device with a stainless steel wire braided structure. Background Technology

[0002] In the field of elevator safety protection, the car buffer device is a key component that reduces the impact on the car and protects passenger safety in the event of an accidental fall or excessive speed descent, directly affecting the safety and reliability of elevator operation. Stainless steel wire braided elevator cars, as a lightweight and high-strength new type of car structure, are widely used in scenarios such as elevator retrofitting in older residential buildings and low-speed home elevators, placing higher demands on the buffer devices adapted to their installation spaces.

[0003] The buffer devices used in existing stainless steel wire braided elevator cars are mainly divided into three categories: hydraulic buffers, spring buffers, and polyurethane buffers. Hydraulic buffers and spring buffers have excellent buffering performance and strong stability, but they are relatively long and bulky, requiring a high depth of the installation pit, and are generally not suitable for the installation conditions of shallow pit elevators. On the other hand, polyurethane buffers are small in size and occupy little installation space, which can meet the installation requirements of shallow pit elevators. Therefore, they are widely used in low-speed elevators installed in homes and old residential areas.

[0004] The polyurethane buffers used in low-speed elevators installed in homes and older residential areas generally rely on the deformation of the material itself to achieve buffering. The buffering stroke is short and the energy absorption capacity is limited. When faced with the impact of an accidental elevator fall, the buffering effect is poor and it is difficult to ensure passenger safety. At the same time, after being impacted, the polyurethane buffer will cause its mounting base to vibrate. Long-term impact can easily lead to problems such as the decay of buffering performance and loosening of connecting bolts, further reducing the reliability of the device and its overall service life. Summary of the Invention

[0005] The purpose of this invention is to provide an elevator car buffer device with a stainless steel wire braided structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an elevator car buffer device with a stainless steel wire braided structure, comprising a base plate, a mounting base and bolts, wherein a polyurethane buffer is installed on the mounting base, a pressure seat is slidably connected to the top of the mounting base, multiple sets of pressure rods are rotatably installed on the side wall of the pressure seat, a support seat is installed on the mounting base, and a sliding seat that slidably connects with the pressure rods is rotatably installed on the support seat. The base plate is provided with a locker and a hydraulic buffer. The end of the hydraulic buffer is connected to a push plate with a mating block on its outer wall. The outer end of the pressure rod is provided with a mating wheel that mates with the mating block. The base plate is provided with a pressure divider for limiting the support seat and a transmission mechanism that mates with the pressure rod to drive the locker and the pressure divider. The locking device includes a sliding frame that slides on the base plate and a spring 1 installed inside the base plate and connected to the sliding frame. A movable frame for limiting the bolt is slidably provided at the end of the sliding frame. A spring 2 installed inside the sliding frame is connected to the inner wall of the movable frame. A synchronizing block is installed on the side wall of the movable frame, and a lower baffle that cooperates with the synchronizing block is provided on the side wall of the sliding frame. After the movable frame slides into the sliding frame, the lower baffle will press against the top surface of the mounting base.

[0007] Preferably, two sets of locking devices are symmetrically installed on the base plate. The two sets of locking devices cooperate to fix the position of the mounting base, and the locking devices restrict the top of the bolt on one side of the mounting base. The pressure seat is located above the polyurethane buffer, and when the locking device moves to the state of locking the bolt, the pressure seat does not move down to the state of being in contact with the top surface of the polyurethane buffer.

[0008] Preferably, the transmission mechanism is located between the bolt and the support seat. The transmission mechanism includes a limiting seat installed on the top of the base plate, and a lifting frame is slidably installed on the top of the limiting seat. A spring buffer installed on the top of the base plate is connected to one side of the lifting frame, and a pressure plate for pushing the locking device is installed on the other side. A transmission wheel that is in contact with the bottom surface of the pressure rod is rotatably installed on the top of the lifting frame, and a side pusher is installed on the side wall of the lifting frame, located outside the spring buffer, for pushing the pressure divider.

[0009] Preferably, the locking device further includes a slide rod installed at the bottom of the sliding frame and slidably connected to the base plate, and a spring is sleeved on the outer wall of the slide rod. The locking device includes two symmetrical sliding frames, which are fixedly connected by a connecting column, and a push wheel that is rotatably installed in the middle of the connecting column and is in contact with the inclined surface at the bottom of the pressure plate.

[0010] Preferably, the inner wall of the movable frame is connected to multiple springs, and both the movable frame and the lower baffle have an L-shaped cross-section. The side wall of the sliding frame is provided with a sliding groove corresponding to the synchronizing block. After the movable frame slides into the sliding frame, the synchronizing block will push the lower baffle to rotate 90°, so that the end face of the lower baffle presses against the top surface of the mounting seat. The bottom corner of the outer end of the lower baffle is an angled angle. The sliding frame contains a wireless alarm located inside the movable frame. When the movable frame slides into the sliding frame, it will compress the wireless alarm.

[0011] Preferably, the hydraulic buffer is symmetrically arranged on the base plate, and the hydraulic buffer and the base plate are arranged parallel to each other. In a static state, the push plate and mating block at the end of the hydraulic buffer are separated from the mating wheel.

[0012] Preferably, the top surface of the push plate is higher than the plane where the top of the support base is located, and the bottom surface of the mating block on the outer wall of the push plate is designed with an incline, and the mating block is located above the mating wheel.

[0013] Preferably, the pressure divider includes top support blocks rotatably mounted on the base plate and located on both sides of the bottom end of the support base, and the base plate is provided with torsion springs corresponding to the top support blocks. A sprocket is coaxially mounted on the bottom end of the top support block, and a chain for connecting the two sprockets is provided inside the base plate.

[0014] Preferably, when the top support block is stationary, it is completely offset from the support base, and the top corner of the top support block is in contact with the bottom inclined surface of the side pusher. After the side pusher moves down, its side wall will be in contact with the side wall of the top support block, thus restricting the side wall of the top support block. In this state, the bottom surface of the top support block is in contact with the bottom top surface of the support base, which is used to share the upward pressure borne by the support base.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through a three-stage combined buffer structure of polyurethane, hydraulic pressure, and springs, completely solves the defects of traditional single polyurethane buffers, such as insufficient energy absorption, short buffer stroke, and large impact. It absorbs the kinetic energy of the elevator falling step by step, resulting in a gentler buffer and stronger shock absorption effect. It significantly improves the safety and passenger protection of the stainless steel wire braided car during a fall. This invention uses impact to link the transmission mechanism, which synchronously drives the locking device and pressure divider to act at the moment the car hits the pressure seat. It does not require electrical control, sensors, or additional power. The pure mechanical linkage has a fast response and precise timing, realizing the integrated synchronous execution of buffering, locking, and pressure dividing. It is stable and reliable in operation with an extremely low failure rate.

[0016] 2. This invention employs a dual-mode locking device. Under normal conditions, it locks the bolts to prevent loosening. When the bolts have loosened, it automatically switches to an emergency locking mode that tightens the mounting base, simultaneously triggering a wireless remote alarm. This dual-mode protection not only prevents loosening but also provides emergency reinforcement in case of malfunction and timely notification to maintenance personnel. The buffer device is securely installed, significantly improving the safety of elevator operation. Furthermore, this invention includes a pressure divider that automatically rotates the top support block to the bottom of the support base upon impact, evenly distributing the rebound impact force. This effectively reduces the load at the connection between the support base and the base plate, minimizing fatigue damage caused by long-term impacts and significantly improving the overall structural strength and service life of the device.

[0017] 3. This invention uses the linkage transmission of multiple sets of pressure rods, sliding seats and matching wheels to smoothly convert vertical impact force into lateral driving force, so that the buffer and protection mechanisms at all levels can intervene in an orderly manner, avoid instantaneous overload impact, and make the force more reasonable and the movement smoother. It is suitable for shallow pit elevator installation space, does not increase the pit depth requirement, and meets the safety protection needs of shallow pit scenarios such as elevator installation in old communities and home elevators.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-7 The present invention provides the following technical solution: an elevator car buffer device with a stainless steel wire braided structure, including a base plate 1, a mounting base 2 and bolts 4. A polyurethane buffer 3 is installed on the mounting base 2. A pressure seat 5 is slidably connected to the top of the mounting base 2. Multiple sets of pressure rods 6 are rotatably installed on the side wall of the pressure seat 5. A support seat 7 is installed on the mounting base 2, and a sliding seat 8 that slides with the pressure rods 6 is rotatably installed on the support seat 7. A locker 10 and a hydraulic buffer 11 are provided on the base plate 1. A push plate 12 with a mating block 13 on the outer wall is connected to the end of the hydraulic buffer 11. A mating wheel 14 that mates with the mating block 13 is provided at the outer end of the pressure rod 6. A pressure divider 15 for limiting the support seat 7 and a transmission mechanism 9 that mates with the pressure rod 6 to drive the locker 10 and the pressure divider 15 to run are provided on the base plate 1.

[0022] In one embodiment of the present invention, the locking device 10 includes a sliding frame 101 slidably mounted on the base plate 1 and a spring 103 installed in the base plate 1 and connected to the sliding frame 101. A movable frame 106 for limiting the bolt 4 is slidably mounted at the end of the sliding frame 101. A spring 107 installed in the sliding frame 101 is connected to the inner wall of the movable frame 106. A synchronizing block 108 is installed on the side wall of the movable frame 106. A lower baffle 109 that cooperates with the synchronizing block 108 is provided on the side wall of the sliding frame 101. After the movable frame 106 slides into the sliding frame 101, the lower baffle 109 will press against the top surface of the mounting base 2. Two sets of locking devices 10 are symmetrically mounted on the base plate 1. The two sets of locking devices 10 cooperate to fix the position of the mounting base 2, and the locking devices 10 limit the top of the bolt 4 on one side of the mounting base 2. The pressure seat 5 is located above the polyurethane buffer 3, and when the locking device 10 moves to the state of locking the bolt 4, the pressure seat 5 does not move down to the state of being in contact with the top surface of the polyurethane buffer 3; the locking device 10 also includes a slide rod 102 installed at the bottom of the sliding frame 101 and slidably connected to the base plate 1, and a spring 103 is sleeved on the outer wall of the slide rod 102; the locking device 10 includes two symmetrical sliding frames 101, and the sliding frames 101 are fixedly connected by a connecting column 104, and a push wheel 105 that is in contact with the bottom inclined surface of the pressure plate 94 is rotatably installed in the middle of the connecting column 104; the movable frame Multiple springs 107 are connected to the inner wall of the movable frame 106. Both the movable frame 106 and the lower baffle 109 have an L-shaped cross-section. The side wall of the sliding frame 101 has a groove corresponding to the synchronizing block 108. After the movable frame 106 slides into the sliding frame 101, the synchronizing block 108 will push the lower baffle 109 to rotate 90°, so that the end face of the lower baffle 109 presses against the top surface of the mounting base 2. The bottom corner of the outer end of the lower baffle 109 is beveled. A wireless alarm is installed inside the sliding frame 101, located inside the movable frame 106. When the movable frame 106 slides into the sliding frame 101, it will press against the wireless alarm. The two sets of locking devices 10 operate synchronously, which can directly lock the bolt 4. When the bolt loosens, it automatically switches to the emergency locking mode of pressing the mounting base 2 and triggers an alarm at the same time, providing double protection to prevent the installation structure from loosening during the impact.

[0023] In one embodiment of the present invention, the transmission mechanism 9 is located between the bolt 4 and the support seat 7. The transmission mechanism 9 includes a limiting seat 91 installed on the top of the base plate 1, and a lifting frame 92 is slidably installed on the top of the limiting seat 91. A spring buffer 93 installed on the top of the base plate 1 is connected to one side of the lifting frame 92, and a pressure plate 94 for pushing the locker 10 is installed on the other side. A transmission wheel 95 that is in contact with the bottom surface of the pressure rod 6 is rotatably installed on the top of the lifting frame 92, and a side pusher 96 located outside the spring buffer 93 and used to push the pressure divider 15 is installed on the side wall of the lifting frame 92. When the pressure rod 6 is pressed down, it directly drives the transmission wheel 95 and the lifting frame 92 to move down. One action synchronously triggers the locker 10 and the pressure divider 15. No additional power source is required. The action response is fast and the timing is precise. Buffering and protection are started simultaneously.

[0024] In one embodiment of the present invention, the hydraulic buffer 11 is symmetrically arranged on the base plate 1, and the hydraulic buffer 11 and the base plate 1 are arranged parallel to each other. In the static state, the push plate 12 and the mating block 13 at the end of the hydraulic buffer 11 are separated from the mating wheel 14. The top surface of the push plate 12 is higher than the plane where the top of the support base 7 is located, and the bottom surface of the mating block 13 on the outer wall of the push plate 12 is designed with an incline, and the mating block 13 is located above the mating wheel 14. After the pressure rod 6 rotates to a certain angle, it automatically triggers the hydraulic buffer 11, forming a progressively stronger damping energy absorption effect to avoid instantaneous overload during impact and improve buffer stability.

[0025] In one embodiment of the present invention, the pressure divider 15 includes a top support block 151 rotatably mounted on the base plate 1 and located on both sides of the bottom end of the support base 7. The base plate 1 is provided with a torsion spring corresponding to the top support block 151. A sprocket 152 is coaxially mounted on the bottom end of the top support block 151, and a chain 153 for connecting the two sprockets 152 is provided inside the base plate 1. When the top support block 151 is stationary, it is completely offset from the support base 7, and the top corner of the top support block 151 is in contact with the bottom inclined surface of the side push frame 96. After the side push frame 96 moves down, its side wall will be in contact with the side wall of the top support block 151, which restricts the side wall of the top support block 151. In this state, the bottom surface of the top support block 151 is in contact with the bottom top surface of the support base 7, which is used to share the upward pressure borne by the support base 7. The bottom corner of the top support block 151 is chamfered to facilitate its rotation to the top surface of the bottom of the support base 7. The two top support blocks 151 move simultaneously under the synchronous drive of the sprocket 152 and the chain 153, evenly distributing the rebound impact force, reducing the load at the connection between the support seat 7 and the base plate 1, and improving the overall fatigue life of the device.

[0026] Working principle: When the stainless steel wire braided frame elevator car buffer device is in normal standby mode, the base plate 1 is fixed to the mounting base 2 by bolts 4, the polyurethane buffer 3 is in a free state, the pressure seat 5 is at the highest point, and the pressure rod 6, support seat 7, and sliding seat 8 all maintain their initial positions; the locking device 10, transmission mechanism 9, and pressure divider 15 are not under force, the locking device 10 does not contact the bolts 4, and the pressure divider 15 does not contact the support seat 7; this design can ensure that the locking device 10 and pressure divider 15 are not under continuous pressure in normal state, avoiding fatigue failure, while the bolts 4 and support seat 7 are not subject to additional constraints, which facilitates daily inspection, maintenance, and replacement; When the stainless steel wire braided elevator car falls unexpectedly and hits the pressure seat 5, causing it to move downward, the pressure seat 5 first drives multiple sets of pressure rods 6 to move synchronously. The multiple sets of pressure rods 6 slide and rotate with the sliding seat 8 as the fulcrum. At this time, the end of the pressure rod 6 near the pressure seat 5 moves downward, causing the bottom of the pressure rod 6 to squeeze the transmission wheel 95 of the transmission mechanism 9, forcing the lifting frame 92 to slide downward along the limit seat 91, thus triggering the entire set of protection and buffer logic. When the lifting frame 92 moves down, it will drive the pressure plate 94 to descend synchronously, causing the bottom slope of the pressure plate 94 to press the push wheel 105. The push wheel 105 pushes the two sliding frames 101 to move along the slide rod 102 towards the mounting seat 2 through the connecting column 104. At this time, the spring 103 is compressed. If the bolt 4 is in a normal state at this time, the movable frame 106 will move to the top of the bolt 4 as the sliding frame 101 slides, so that the bottom surface of the movable frame 106 is in contact with the top of the bolt 4, directly locking the bolt 4, preventing the bolt 4 from loosening or falling off during impact, and ensuring the stability of the mounting base 2. If bolt 4 is loose at this time, the movable frame 106 cannot move normally above bolt 4. At this time, the side wall of the movable frame 106 will be squeezed against the side wall of bolt 4, forcing the movable frame 106 to retract into the sliding frame 101, causing the spring 107 to be compressed. Synchronization block 108 moves with movable frame 106, pushing lower baffle 109 to rotate 90°, so that its bottom surface presses tightly against the top surface of mounting base 2, forcibly fixing mounting base 2. At the same time, movable frame 106 will squeeze the internal wireless alarm, emitting a remote alarm to remind maintenance personnel that bolt 4 has loosened, realizing real-time fault monitoring. When the lifting frame 92 moves down, it will simultaneously drive the side push frame 96 to move downward. The bottom inclined surface of the side push frame 96 presses against the top support block 151, causing it to rotate against the torsion spring force. Under the synchronous action of the sprocket 152 and the chain 153, the top support blocks 151 on both sides rotate into place at the same time. The bottom surface of the top support block 151 is in contact with the bottom top surface of the support base 7, directly bearing the upward rebound force transmitted to the support base 7 by the pressure rod 6 and the sliding seat 8, greatly distributing the load and reducing the load at the connection position between the support base 7 and the base plate 1. Once the pressure plate 94 and the side pusher 96 have moved into place, they will respectively conform to the side wall of the pusher 105 and the top support block 151 and stop moving, ensuring that the locking and support positions are accurate, do not exceed the limits, and do not fail. As the pressure seat 5 continues to move downward, the pressure rod 6 moves towards the sliding seat 8. The mating wheel 14 at the end of the pressure rod 6 contacts the outer wall of the push plate 12 and the bottom inclined surface of the mating block 13, pushing the push plate 12 backward and activating the hydraulic buffer 11, entering the hydraulic damping energy absorption stage. Subsequently, the pressure seat 5 comes into contact with the top surface of the polyurethane buffer 3 and begins to compress and absorb energy. At the same time, the lifting frame 92 is also continuously squeezing the spring buffer 93 to further absorb the impact kinetic energy. Ultimately, a four-fold combined buffer system is formed, consisting of polyurethane buffer 3, hydraulic buffer 11, spring buffer 93, and transmission friction pressure divider, which gradually disperses, dissipates, and eliminates the kinetic energy of the car falling, greatly improving the buffering effect and passenger safety. After the car rebounds and rises, the pressure seat 5 loses pressure, and the polyurethane buffer 3, hydraulic buffer 11, and spring buffer 93 reset synchronously, driving the pressure seat 5, pressure rod 6, and lifting frame 92 back to their initial positions; the locking device 10 retracts under the action of spring 103, and the pressure divider 15 rotates under the action of torsion spring, and all mechanisms return to standby state, waiting for the next protection action.
